Funktioner i appen Lägesinställningar

Lägesinställningar i TI-84 Evo bestämmer hur tal och grafer visas. Inställningar sparas när du stänger av räknaren.

Välj ikonen Lägesinställningar på startskärmen  eller tryck på j på tangentbordet för att öppna lägesinställningsskärmen.

Tryck på nedåtpil- eller uppåtpiltangenten för att navigera mellan olika inställningsalternativ. Tryck på höger piltangent och vänster piltangent för att flytta markören till de inställningar du vill ange och tryck på =.

Se exemplen nedan för en översikt av de olika inställningar som finns i appen Lägesinställningar.

Change graph mode setting

Select Mode Settings icon  or press the j key.

  • Change among Function, Parametric, Polar and Sequence modes.

Graphing modes define the graphing parameters.

Graph Icon changes depending on the Graph Type Mode Setting:

 FUNCTION: graphing mode plots functions, where Y is a function of X.

 PARAMETRIC: graphing mode plots relations, where X and Y are functions of T.

 POLAR: graphing mode plots functions, where r is a function of θ.

 SEQ: (SEQUENCE) graphing mode plots sequences. Three sequences are available: u, v, and w, with an option of the independent variables of n, n+1, and n+2.

Change to Graph Table view (split screen)

When a function is entered in the Y= editor, you can view a table of values by pressing a Ä.

Note: The table setup, a Ä, determines how table values are displayed. Check the table setup values if the table results are not in expected format of fraction. Using a mix of decimal and fractions will not retain fractions.

Change to Horizontal View (horizontal split screen)

In horizontal mode, the bottom zone can be the function editor, list editor, the table, or the calculator. The top area is always the graph screen. Change the bottom view by selecting the desired application using the icons on the home screen or the appropriate key.
